Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The line 'opens nothing by itself' adds genuine value by confirming the tool has no side effects, consistent with readOnlyHint=true and destructiveHint=false. It also discloses the return shape (step-by-step screens, buttons, fields) and flags API limitations, though the third sentence never says what those limits actually are.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The first two sentences are well front-loaded and earn their place. The trailing sentence 'Okendo's official API: Okendo has an official API, but with limits (checked 23 Oct 2026)' is repetitive and vague, adding a date stamp without actionable content, and the semicolon chaining makes the flow slightly awkward.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter guide tool with no output schema, the description covers the essential contract: what it returns, that it is non-mutating, and which tool family performs the action. Remaining gaps, such as authentication prerequisites and the unspecified API limits, are minor for this tool's complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters, so the schema baseline of 4 applies, but the description never addresses the obvious ambiguity of how the target review is identified when no review ID is accepted. It adds no parameter meaning because there is none to add, and leaves the identification question implicit.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('Reply to review in the user's own Okendo account') and crucially clarifies that the tool itself only returns step-by-step instructions rather than performing the reply. That distinction differentiates it from action-style siblings like okendo_publish_review, though it does not name those siblings directly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear routing: call this to get the screens/buttons/fields, then execute with the cotlet_browser_* tools in the Okendo Cloud Browser. What is missing is explicit exclusion guidance — e.g., when to use okendo_answer_product_question instead, or whether an already-open browser session is required.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
